Superstar Mets outfielder Yoenis Cespedes also departed in the fourth inning with a hamstring injury, further crippling a Mets club that has lost six straight games, and 10 of 11.
Suzuki's homer was the biggest blow, knocking Harvey out of the game after only 4 1/3 innings. But the Braves also took advantage of a career-high-tying five walks from Harvey, who did not learn until Thursday morning that he would be starting.
The Mets stayed in the game until late thanks to a two-run rally off R.A. Dickey in the fourth inning, and a Jose Reyes homer in the fifth, but were unable to do enough damage against a quartet of Braves relievers.
